Abstract
The utility model relates to an internal star wheel provided with spherical ball grooves and used in an auto transmission shaft device. The internal star wheel includes an inner circle matched with an auto transmission shaft, wherein 6 spherical surface shapes are uniformly distributed on the outer side of the inner circle, an upper plane of the inner circle is a locating reference plane, a lower plane of the spherical surface shapes is a base plane, an inner ball groove is formed between every two spherical surface shapes, and the inner ball grooves take the shapes of arc grooves. The utility model has the benefits as follows: as the six ball grooves uniformly participate in the transmission at the same time, the bearing capacity is high; furthermore, the internal star wheel has a compact structure, is convenient to demount and mount, is worn less, has a long service life, and can be applied to various types of steering transmission devices.
Description
Technical field
The utility model relates to a kind of star-wheel that is used for the vehicle transmission shaft device, relates in particular to the interior alley structure of this star-wheel.
Background technique
Tradition curved grooved type transmission device adopts initiatively fork, parts such as driven fork; The pressure assembling, dismounting is inconvenient.Owing to have only two steel ball power transmissions, when counter-rotating, turn to dumb, gapped, noise is big; And steel ball and curved surface groove unit pressure are big, and be easy to wear and vibrations are big, influences physical life, is unfavorable for modern industry.
The model utility content
The utility model technical issues that need to address have provided a kind of star-wheel that the vehicle transmission shaft device has the ball-type alley that is used for, and are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technological scheme:
The utility model comprises: the interior circle that matches with truck drive shaft; Even 6 spherical shape that distribute in the outside of circle in described; The last plane of circle is a location datum plane in said; The lower plane of said spherical shape is a bottom plane; Form alley between per 2 spherical shape; Alley is shaped as an arc groove in said.
Compared with prior art, the beneficial effect of the utility model is: owing to there are six alleys to participate in simultaneously uniformly transmission, and so bearing capacity is strong, compact structure, easy accessibility, it is little to wear and tear, life-span length and can be used in the steering transmission linkage of various models.
Description of drawings
Fig. 1 is the utility model stereogram.
Fig. 2 is the floor map of Fig. 1.
Fig. 3 is that the A-A of Fig. 2 is to schematic representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Visible by Fig. 1, Fig. 2, Fig. 3: the utility model comprises: the interior circle 1 that matches with truck drive shaft; Even 6 spherical shape 2 that distribute in the outside of circle 1 in described; The last plane of circle 1 is a location datum plane 3 in said; The lower plane of said spherical shape 2 is a bottom plane 5; Form alley 4 between per 2 spherical shape 2; Alley 4 is shaped as an arc groove in said.
Its outer surface has six arc grooves in the utility model, alley in forming, and six steel balls are contained in respectively in six pairing spaces of interior alley, and are limited in the same plane by the ball cage.
When adopting the utility model work, power is by truck drive shaft, steel ball and out star wheel output.Because angle between transmission output shaft and the live axle main reducing gear input shaft and distance change; Therefore to solve with strain device; And the ball-type alley is parts of realizing the varied angle transmission of power, allows than Angular Displacement between steel ball and the ball-type alley, can eliminate driving shaft and the torsional vibration that cause asynchronous with the driven shaft instantaneous angular velocity; Guarantee the synchronous of diaxon rotating speed, and remaining constant speed property.And the pin moulding is once ground in the processing of the interior alley of ball-type, when speed change is rotated and fierce impulsive load is arranged, can bear big contact stress, and sphere contact smoothly having solved the pockmark that rolling causes, having peeled off and spot corrosion, and the contact situation is still good.Ball-type alley structure is the necessary structure in the electrodeless variable-speed power transmission process, and the quality of its contact stress and service behaviour directly has influence on the functional reliability of car load.The ball-type alley can change the direction of transmission axis at any time, participates in transmission simultaneously uniformly because of six alleys are arranged, so angular displacement is big, and revolution; Turn to nimbly and freely, bearing capacity is strong, compact structure; Easy accessibility, it is little to wear and tear, and the life-span is grown and can be used in the motor turning transmission device of various models.
